Choosing the Right Strobe

I have a Nikon Coolpix P7000 and am planning on purchasing a Fantasea housing for it. I also need to get an appropriate strobe. I plan on being a generalist with regard to the types of pictures I take (macro, wide angle, etc.). I will not be a heavy user in that I typically take one dive trip per year. I have been looking at the Ikelites and the Sea and Seas, however, I am open to suggestions.
